Hi, thanks for a great tutorial!

Does the firmware of the QQ-S need to be updated/replaced as well, or will these drivers run with stock FW?

Thanks again!

You can either, flip the orientation of the plug on the board, or modify config values in the firmware config file and re-flash the firmware. I chose to flip the plug so I would need to mess with flashing firmware.

Do you need to reverse the plug for a 2209? Difference between 2208 and 2209 for my QQS Pro?
